The SetBlendState function sets a blend state.

Syntax

PFND3D10DDI_SETBLENDSTATE Pfnd3d10ddiSetblendstate;

void Pfnd3d10ddiSetblendstate(
  D3D10DDI_HDEVICE Arg1,
  D3D10DDI_HBLENDSTATE Arg2,
  const FLOAT[4],
  UINT Arg4
)
{...}

Parameters

Arg1

hDevice [in]

A handle to the display device (graphics context).

Arg2

hState [in]

A handle to the blend state to set.

FLOAT[4]

pBlendFactor [in]

A four-element array of single-precision float vectors that the driver uses to set the blend state.

Arg4

SampleMask [in]

A sample format mask.

Return value

None

Remarks

The driver can use the pfnSetErrorCb callback function to set an error code.

The driver should not encounter any error, except for D3DDDIERR_DEVICEREMOVED. Therefore, if the driver passes any error, except for D3DDDIERR_DEVICEREMOVED, in a call to the pfnSetErrorCb function, the Microsoft Direct3D runtime will determine that the error is critical. Even if the device was removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interfered with the operation of SetBlendState (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
